A 14-year-old Long Island boy who was last seen going for a run was found dead in a wooded area Wednesday morning — and authorities believe he committed suicide.

Nickolas Donnelly left his Shoreham home around 10 a.m. Tuesday wearing a gray t-shirt, officials said.

His body was found nearly 24 hours later in a wooded area about a mile from his home.

The victim’s uncle, Donald Donnelly Jr., said bullying played no role in his nephew’s apparent suicide. “He always greeted you with a smile on his face and went out of his way to say hello,” Donnelly Jr. said in a statement. “He had many friends and will be missed by his two brothers, Luke, who is a junior, and Kyle, who is in 6th grade.”

An exact cause of death was not immediately known.

A candlelight vigil in honor of Connelly had been scheduled for Thursday afternoon. The boy’s devastated friends and family members took to social media as word of his apparent suicide got out.  “I’m broken,” a friend of the victim said on Facebook.
